The industries we serve

Frequently asked questions

Answers to the most common questions about our products and services

The archived manufacturer manual describes 3300/3301. It supports identification of existing systems; new-purchase availability needs separate confirmation.

Sensor, sensor cable, adaptation board, controller, signal cable and power supply. The adaptation board participates in calibration, not just connection.

Not automatically. The manual requires adaptation-board changes and a calibration check when head type, cable length or target material changes.

No. It is specified for ranges up to 1 mm. Response and resolution depend on settings; static resolution is not the high-speed specification.

No. DT3300 uses ±12 V and 5.2 V; DT3301 specifies 11–32 VDC. Match power and synchronization cables as well.
